Rumor has it that Apple’s next generation smartphone, the iPhone 5S, will have support for LTE-Advanced, a standard that offers double speeds as compared to the current 4G LTE standard.

The LTE-Advanced or LTE-A standard started receiving much publicity a couple of weeks back when it was rumored that Samsung would be launching a faster Galaxy S4, one with LTE-A support and Qualcomm’s Snapdragon 800 processor. Samsung did indeed launch this device, which is the only available for customers in South Korea, where SK Telecom’s LTE-A network went live for users last week.

A new Korea Times report claims that Apple is having discussions with SK Telecom to launch an LTE-A capable iPhone 5S later this year. To make this happen, the company is expected to put in a new Qualcomm baseband chip that was announced earlier this year. The chip will enable Apple’s upcoming smartphone to support all 2G, 3G, 4G, LTE and LTE-Advanced networks. An unnamed SK Telecom has been cited in the report as saying that Apple has no reason not to bring LTE-A support to the next generation iPhone.

LTE-A networks are rare right now, even major carriers in the U.S. have yet to start rolling out their own LTE-A networks. This standard will theoretically offer data speeds of up to 150Mbps on mobile devices, which is substantially greater than what speeds the current 4G LTE standard is capable of offering. As per the latest rumors, Apple will launch the iPhone 5S this September.
